Catenary Wire: Types and Uses

Catenary wire can be used in various applications, from domestic commercial and industrial. It has many different uses and can be bought in various different lengths, and as different types of wire as well. Here, learn more about what catenary wire is and what the name means, as well as exploring the different types of wire and what they can be used for.

In simple terms, the word ‘catenary’ simply means the curve that is created when wire (or chain) is supported at either end. It is a broad term for any kind of wire that is assembled like this – it might be used for electrically wired transportation, overhead electricity, light fittings and more. The catenary wire is used to install wire rope overhead and some of the applications in everyday life include Christmas lighting, hanging heavy curtains and suspending heavy power cables. Sometimes it might be installed into masonry or concrete, in which case it might be supplied in a kit form with the required fittings.

Different Types of Catenary Wire

There are two main types of catenary wire you may come across: galvanised catenary cable and stainless steel catenary wire. Here are the key differences to consider so you can purchase the right kind of catenary wire depending on your operations.

When catenary wire is galvanised, what this means is that it has a protective zinc coating that has been applied over the wire. The zinc will provide protection, preventing the wire rope corroding or going rusty over time, especially when used in certain conditions or out of doors. While stainless steel catenary wire will also not rust (it will be naturally resistant due to the material), the zinc will still offer a level of additional protection that can be beneficial. If the equipment and wire is mostly going to be used in an outdoors environment, then galvanised catenary wire might be preferable to give it the best chance of lasting a long time.

In fact, many people tend to use catenary wire out of doors for applications like supporting cables along train tracks, and other kinds of overhead wiring. This means that galvanised wire may be the better option – if you are at all unsure, it is always best to check with the supplier to make sure you will be getting the right kind of wire to meet your needs. Both types of catenary wire should be made from high grade steel, which can be used safely in various internal and external environments, so it is always best to check. Any experienced supplier will have come across these questions many times before and will be able to offer comprehensive advice and talk you through the option. They will also be able to talk to you about how much catenary wire you will need to buy to meet your needs, and they will be able to supply the wire cut to your exact length and specifications where their more standard wire sizes and lengths will not be a suitable fit.
